Safety Integrated - Industry - Siemens

Process: Safety program
Precondition
The user can passivate and automatically reintegrate F-modules
via the safety program. The PASS_ON variable is used for
this.
State
F-module not passivated (1)
In the safety program: PASS_ON = 1
F-module passivated (2)
In the safety program: PASS_ON = 0
F-module reintegrated (3)
Process sequences
The F-module is passivated with "PASS_ON = 1". The F-module
is automatically reintegrated with "PASS_ON = 0".
The following figure and table illustrates the process sequence.
Number in brackets indicates the state.
